Has this happened to you?

The Insta360 X6 exports 360-degree photos at 15520×7760, versus the X5 at 11904×5952. The file size is also larger, with images around 76MB versus around 30MB on the older camera.

When I first tried to upload an X6 image to Facebook, most worked, but a few would error out. They were large files, so I tried compressing them down (same image size, but reduced file size) thinking that was the problem. This allowed me to upload them. Problem solved.

But then I had this batch of five images… All fail. Even when I downsized the files to around 26MB each, Facebook still rejects them.

It is clearly not the resolution, since some work.

Does anyone know what the rules are here?

If I figure it out, I will update this post. Until then…
